Mr-Glass Window Replacement: The Clewiston Owner’s Guide
Mr-Glass window replacement in Clewiston typically runs $340-$780 per opening installed, depending on series, size, and whether the frame is salvageable. We stock Mr-Glass-compatible sash packs, balances, and full-frame units on our Clewiston truck, and most replacements are measured, written up, and scheduled within a single visit. Homeowners usually discover the failure when a window won’t stay open, fogs between the panes, or the sash drops like a guillotine the moment the latch releases.
Which Mr-Glass Models This Applies To
Mr-Glass produces several window lines common in South Florida builds from 2012 forward, and the part you need depends on which series is in your wall. The 3000 Series single-hung and 5000 Series horizontal roller are the two we see most often in Clewiston homes, particularly in the developments south of West Sugarland Highway where Mr-Glass units were spec’d heavily between 2015 and 2021.
To identify your series, check the etched mark in the glass corner or the label on the frame head. The 3000 Series uses a 2-5/8″ frame depth with a constant-force balance; the 5000 Series runs a 3-1/4″ frame with a tandem roller system. Getting this wrong means ordering a sash that won’t seat or a balance that won’t tension correctly.
We carry both OEM Mr-Glass components and quality aftermarket equivalents from CWS and ES Windows where the spec matches. For the 3000 Series constant-force balance, the OEM part and the CWS equivalent perform identically in our field testing; for the 5000 Series tandem roller, we prefer OEM because the axle diameter tolerance is tighter and aftermarket rollers tend to flat-spot within 18 months on Clewiston’s dirt-road-adjacent properties. Sightline Windows & Doors Clewiston is an independent service provider, not affiliated with Mr-Glass.
Before
AfterSigns Your Mr-Glass Window Replacement Is Failing
- The sash won’t stay up or slams shut. This is the constant-force balance failing, usually from corrosion at the hook end where Clewiston’s humidity meets the metal. The balance spring loses tension gradually; by the time the sash drops, the internal coil is already kinked.
- Fog or moisture between the glass panes. The insulated glass unit (IGU) seal has failed. In Clewiston, this accelerates on west-facing walls where afternoon heat builds pressure inside the air space. The desiccant saturates, and the glass is no longer a thermal barrier.
- Rolling window drags or sticks in the track. The tandem rollers have flat-spotted or the axle bearings have ingested grit. We see this often on homes near the cane fields where airborne particulate is higher than the coast.
- Visible frame distortion or corner gaps. The vinyl has thermally cycled beyond its design limit. Mr-Glass frames in dark colors installed without adequate expansion clearance will show this first on the south and west elevations.
- Air infiltration at the meeting rail even when latched. The interlock weatherstrip has compressed or the sash has settled out of square. This is gradual; homeowners notice it first on windy days when the AC runs constantly.
Replacement Cost & What’s Included
| Component | Typical Range (Clewiston) |
|---|---|
| Constant-force balance (3000 Series) | $180-$290 |
| IGU replacement (sash-in-frame) | $340-$520 |
| Tandem roller set (5000 Series) | $220-$340 |
| Full sash replacement | $420-$680 |
| Complete frame-out, new Mr-Glass unit | $620-$780 |
These are installed prices, inclusive of the measured survey you keep, the written scope, and the photo record. The range reflects opening size, second-story access, and whether the existing frame is plumb and square. If we pull trim and find rot in the rough opening, we stop, document, and quote the repair before proceeding. Haven Clause 1: the written price before any work starts. Haven Clause 5: no surprises.
Every replacement carries our 365-Day Done Right Promise. If the balance tension drifts or the IGU fogs, we return and make it right.
DIY or Call Us?
An owner can safely check the series marking and measure the visible sash dimensions with a tape. What you cannot safely do is remove a constant-force balance under tension or cut out an IGU without proper glazing points and setting blocks. The balance stores enough energy to lacerate a hand or launch a sash across the room. We’ve seen both.
DIY IGU replacement also fails because the replacement unit must be ordered to the exact daylight opening minus 1/8″ perimeter, and the setting blocks must sit at the correct quarter-points or the glass will crack in the first heat cycle. Measure it right the first time. Everything after that is just paperwork.
If you’re holding a dropped sash or staring through fog, call (863) 509-1135. We’ll measure, write the price, and schedule. The estimate is free.
FAQs
In Clewiston, a constant-force balance typically lasts 8-12 years, and an IGU seal 10-15 years if the window faces east or north. West and south exposures, or homes near unpaved roads where grit enters the track, cut that by 20-30%. Call (863) 509-1135 and we’ll assess what’s actually in your wall.
A failed IGU cannot be repaired; the seal is permanent and the desiccant is saturated. A balance can sometimes be retensioned, but the coil is usually already corroded where we can’t see it, and the repair fails within months. We quote replacement because that’s what lasts. Call (863) 509-1135 for a free second opinion on any other estimate.
A balance replacement takes 45-90 minutes per window. An IGU or sash swap runs 2-3 hours including removal, cleanup, and operational testing. Full frame-outs are a half-day per opening. We arrive with the part, verified against your series, so there’s no return trip.
We carry 3000 and 5000 Series balances, common sash sizes, and IGU patterns for the most frequent Clewiston configurations. For odd sizes or discontinued series, we measure, order from the factory, and return within 5-7 business days. Call (863) 509-1135 to confirm stock for your specific model.
